High Speed Oil Consumption

Like others I have experienced slight oil consumption at higher speeds in the 1100-1200 miles/qt range. As others have proposed I believe that the PCV system is behind this. After reviewing the crankcase ventilation system (see below) I find I am even more inclined in that direction

AN400 K3 crankcase ventilation system:

With the crankshaft whizzing around at 7000+ RPM I can envision a sizable quantity of churned up oil being pulled out via the PCV system. When the weather cools (99.7° here yesterday, 115.9° heat index) I plan on pulling it apart and seeing what I can see...
